To all whom it may concern.: 1

Be it knownthat l, WRIGHT DURYEAyof the city of Brooklyn, in the county of AKings and State of New York, have invented a new and useful lmprovementfin Starch-Depositing Planes or Runs, of which the following is a specification.

My invention relates to planes or runs einployed in starchworks, over which the starchmilk is caused to tlowand on which starchis deposited. Frequently these planes'or runsare a hundred feet or more in. length, and they have but a very slight inclination, which is sucient to secure the most economical result. As such planes or runs fill up with starch their operation becomes more and more wasteful, because the starch deposits in greater quantity near the head of the plane or run, and so increases the inclination of the plane or ru'n, and also because the deposited starch is guttered77 or channeled by the more rapidly-flowin g fluid.

The object of myinvention is to remove these difficulties.

My invention consists in the combination of a series of comparatively short planes or runs arranged One in advance of another, and having between the tail of each plane or run and the head of the next a drop, pocket, or cavity, as more fully hereinafter described.

The invention also consists in the combination of a series of comparatively short planes or runs arranged one in advance of another, and having an adjustable gate at the tail of each plane or run, and an adjustable Weir at the head of the plane or run next in advance.

The invention also consists in the combination, with a series of planes or runs arranged as described, of a drop, pocket, or cavity between the tail of each plane or run and the head of the next, and adjustable gates and weirs, as above described; also, in combination with the said pockets or drops, of stirrers or agitators arranged therein for preventing starch from there depositing.

In the accompanying drawings, Figure l is a sectional view of a series of planes or runs embodying my invention. Fig. 2 is a similar section, on a larger scale, illustrating the tail of one run and the head of thenext; and Fig. 3 is a plan of the parts shown in Fig. 2.

Similar letters of reference indicate corresponding parts inall the figures.-

A A A2 designatethree planes or runs arranged in series', one in advance of another. Any number of planes or runs may be thus arranged, and theyare similar in construction to those now used, save that they are of much less length. At the tail of each plane or run is an adjustable gate, c, tted in guides a, and

'capable of being 'adj usted vertically by means 6o of screws and nuts b'c, or other suitable means. -At the head of the plane'or run next in advance is an adjustable weir, d, which may be raised or lowered in guides d d by means of bolts or screws e and nuts c', or other means.

Between the tail and head of two adjacent planes or runs I have here shown a pocket or drop, Ait, into which the gate a and weir d In said pocket or drop At, I may also arrange arotary stirrer or agi tator, B, in order to prevent starch from there depositing. This stirrer or agitator may be rotated slowly by a belt or a pulley, g. Starch milk is delivered onto thc planes or runs from a tank or vat, C, and flows down and along the series of planes or runs to the end of the series. As the deposit of starch increases the gates and weirs are adjusted upward tr raised in a well-understood manner, and the upper edge of the weir furnishes a permanent and truly horizontal gage or surface over which the starch-milk iiows uniformly from end to end thereof, and in a llin or stratum as thin as desired.

I am aware that the long planes or runs heretofore in use have been provided with adjustable gates, and that a gutter has been provided into which the spent-liquor or glutenwater has been delivered over these gates, and which conducts away the spent-liquor or gluten-water from a number of planes or runs. I do not claim such a construction and combination of parts as of my invention.

By arranging a number of comparatively short planes or runs, one in advance of another, and separated by drops, pockets, or cavities', I secure a much more economical operation than is possible when employing1 a single long plane or run having an inclination which is unbroken and continuous from head to tail roo thereof, and by arranging in each drop, pocket, or cavity a stirrer or agitatorY I prevent the drop or pocket from filling up with starch.

By arranging short planes or runs in a series, one in advance of another, and by employin g not only adjustable gates at the tail of each plane or run, but an adjustable Weir at the head of the next plane or run, I secure a more uniform deposit of starch on each plane or run, and secure a more nearly equal inclination whether the planes or runs are empty or partly lled with starch. I also obviate any tendency to waste, by reason of the water cutting gutters or channels in the starch deposit and forming currents for the gates and Weirs'at adjacent ends of the planes or runs; all such currents are broken up and the flow is again evened or made uniform throughout the entire width of the plane or run.

What I claim as mylinvention, and desire to secure by Letters Patent, is-

1. The combination of a number or series of planes or runs arranged one in advance of another, and having between the tail of each plane or run and the head of the next a drop, pocket, or cavity, substantially as and for the purposeherein described. Y

2. The combination of anumber or series o planes or runs arranged one in advance of another, and having between the tail of each plane or run and the head of the next a drop,

pocket, or cavity, and a stirrer or agitator in each drop, pocket, or cavity, substantially as and for the purpose herein described.

3.' The combination of a series of planes or runs arranged one in advance of another, and having an adjustable gate at the tail of each plane or run and an adjustable weir at the head of the plane or run next in advance, substantially as and for the purpose herein de scribed.

4. The combination, with a series of planes or runs arranged one in advance of another, of a drop, pocket, or cavity between the tail of each plane or run and the head ofthe next plane or run, an adjustable gate at the tail of each plane or run and an adjustable weir at the headof the next plane or run, substantially as and for the purpose herein described.

5. The combination, with a series of planes or runs arranged one in advance of another, and connectedby drops, pockets, or cavities, of an l adjustable gate at the tailof each plane or run,

an adjustable weir at the head of the nextplane or run, and stirrers or agitators in said drops. pockets, or cavities, which prevent the deposit vof starch therein, substantially as and for the
